Research on Land Area Surveying Technology and Land Information System Based on Beidou/GPS Dual Mode Positioning

为提高土地面积测绘的精度、减少测量结果误差,规范土地资源的利用与开发,将北斗/GPS双模定位技术作为核心与支撑,对土地面积测绘技术展开设计与研究,并以此为依据,开展土地信息系统的开发。通过计算卫星信号与接收机距离、土地面积测绘与误差补偿,完成测绘技术的设计。将测绘技术作为基础,进行测量仪选型、土地信息无线通信部署、定位信息获取传输、土地信息系统数据库连接展示,以此实现对系统的开发。通过测试证明了设计的测绘技术测量结果与实际结果的误差较小,可以在实际工作中忽略此误差,将测量结果作为真实结果,同时,综合测试结果可知,本文开发的系统可以达到预期的设计标准与效果。

In order to improve the accuracy of land area surveying,reduce measurement errors,and standardize the utilization and development of land resources,the Beidou/GPS dual-mode positioning technology is used as the core and support to design and research land area surveying technology.Based on this,the development of land information systems is carried out.By calculating the distance between satellite signals and receivers,land area surveying and error compensation,the design of surveying technology is completed.Based on surveying and mapping technology,the selection of measuring instruments,wireless communication deployment of land information,acquisition and transmission of positioning information,and database connection display of land information systems are carried out to achieve the development of the system.Through testing,it has been proven that the measurement results of the designed surveying and mapping technology have a small error compared to the actual results.This error can be ignored in practical work,and the measurement results can be regarded as the true results.At the same time,the comprehensive test results show that the system developed in this article can achieve the expected design standards and effects.
